This is kind of a Tyrannis pro alternative, taranis plus alternative. I have met Terrenas here sitting to kind of show you the difference between these two radios. This is a radio called radio link it's the 89s there's, a previous version of this radio called the 89 that came out last year in 2015, pretty nice radio and in a cheaper alternative than something like the Terrenas or spectrum radios, Πολύ, very easy to use and Link up with the receiver, it does come with the receiver in the box as well. The other things that come along with it are a little tiny DVD. That shows you all the different manuals for all the different radio link: transmitters. They are PDF format and it also comes with a double a battery case. In case you want to use double A's. You can also use a 3s battery on here as well, because it does have a little jst that plugs in nicest thing about this. Is that sometimes you get the polarity mixed around and it has an automatic protection in the radio that will protect it from shorting out your radio, so you're not going to fry your radio. If you plug this in backwards, το οποίο είναι πολύ ωραίο, but it is labeled on the board, positive and negative, so make sure you pay attention when you plug this in also in the Box, you you have a radio transmitter, strap that plugs in right here in the Middle and put that around your neck to make it a little more comfortable when you're flying and it comes with an extra gimbal arm and an extra spring in here as well, just in case one of your Gimbels snaps.

Sometimes the springs in there will will snap in years previous, using radios I've had that issue, so that's pretty nice that they include that now price point on the radio is pretty nice it's around one hundred and forty dollars on our friends over a gear best website. The fr sky compatible radio, this taranis, Plus that I got last year. Είναι γύρω από το 200 mark with one receiver I believe, and it's compatible with fr sky receivers and they're they're similar priced. These guys do make some other receivers various different sizes and range. This one's boasting around 4500 feet max range distance, and this is sort of the midsize receiver that comes along with it's, an r 9 d s. You can look those up on gearbest website and see how much they, Νομίζω, they're around the 15 Σήμα. So pretty cool receiver because it does have s, bus and ppm, so very, very compatible with every pretty much every multi rotor on the market these days now. Another cool thing about this radio is that it does operate on a much lower current level than some of the other transmitters out there. This one's operating on 90 Αλλά, που είναι, is going to give you around 12 hours operating time on this transmitter. If you use in something like a an 1800 milliamp, so that's that's an extremely long operating time, other transmitters that I have operate in 8 για να 9 hour range now. Another nice feature about the radio link 89: s is the response time response time between the receiver and the radio is around 3 milliseconds and that's way faster than some of the other radios on the market you're going to get around 20 20 milliseconds to be exact.

So it is on a very, very high resolution, gimble response time for this radio. Ok, but before we go into the radio let's talk about the switches and the features on this radio externally before we go inside now has a lot of switches on here. You have 10 channels to operate from and the power buttons in the very middle. You have an LED indicator, switch up here. That tells you you're good and it will start blinking if you have a low voltage issue on your battery on the radio. So you have your mode button here which lets you go into the interface and make changes over here you have a dial wheel and a push button in the center, so you can change back and forth there. Also this large button over here it says and on it, but this is essentially the back switch, so this will allow you to get back out of your menus and back to the main area. Τώρα, up top, we have a b c d, και, f g and h switches, and this start with this top one right here. This is a three position switch. This is a two position. F and H is going to be your momentary. Switch G is another three position B is a two position. C is a three position B is 2 and a is 2. You also have pot switches here that can go back and forth and make dial adjustments.

Your trim switches on the very back of it. You have two levers on the back very similar to the trance, but the way that this is set up, the trained us has it on the side, and this one is kind of organ Amma Klee designed because it's right, where your index fingers are and that's pretty Nice, so I can go in here and I feel like I can change those pretty nicely on the back there right where my finger sits. So if you set that switch up on a gimbal, if you have a gimbal lever switch, you can do that for your camera adjustment, that's pretty nice and on the very bottom, we have the USB port for updating your firmware on your 89 s and the last External feature we have on here is the trainer port and you'll plug in your cable here and plug it into another transmitter to set up a student master pilot setup. You can make this one, the master or the slave controller either way, and you can have someone else fly and not worry about crashing now, I'm going to go ahead and show you. The interface in the radio link 89s go ahead and hit the power switch and turn it on and right away. We see that we have a nice color screen here. It is multicolored and it has a variety of settings on the front here we have a few different versions of telemetry on here.

We have our RX power, we don't have it powered up right now, so you're going to see 0, but very very nice. Βλέπετε.. L, your trim modes here and those are set all to Center. If you move them, you'll see that you have actually numbers here that give you positive 20, πού, if you go to the right, it should say negative, so that's kind of nice and you get back to zero here and you'll, see that they're all set to zero. Our transmitters out there on the market that I've seen sometimes they don't, give you that numerical so that you, you sort of don't, know whether you're in the exact centre or notand this is a really nice feature for your trim setup now, it does show you Your model up here it shows you, your radio name. It says radio link right there. You can actually go in and change that as well. If you want to change it to your name, whatever your fpv pilot name might be, you can change it to that and you can also change this from mode 1 σε λειτουργία 2 καθώς και. So if you want to fly mode 2, you can do that either or also up at the very top. You have your battery telemetry and I have a 3s battery in there right now, it's about a 3 SI 50 just for the demo I'm doing. For you guys now to get into the menus, it's very simple: you just press this mode button.

This is probably one of the easiest most intuitive transmitter setups that I've used way more intuitive than the Saran is plus. If you've ever tried to operate the Taranis. Now it took me a few minutes just to over look all of these settings in here and get familiar with it. It only took me just a few minutes to get used to it. We can go into the parameter mode here oops, so I went into the wrong screen. You press the end button to go back. Ok, Τώρα, it's very sensitive, this little wheel, press this enter button again I'll go into the parameter settings. I can change the language, and this is where you change from mode 1 σε λειτουργία 2. Very simply just tap that and you can change you can go all the way to mode 4. Looks like stick mode 4, so we're going to leave it in stick mode. 2 RF backlight. You can change how bright it is the brightnessand this is where you change your user name as well, so right now, we're just going to leave it set to radio link. You also have an apple tidge alarm on here, so it'll vibrate or give you an alarm if the battery gets low and you have a lock screen setup, you can also turn the sound off this little beeping is kind of annoying you. We can do that. That'S kind of nice and we have a nice quiet radio.

Now I can go back and I'll go into model selection. You can change the different aircrafts that you're on and you can also copy one model down to the next one available I'm going to go back out of that. One change your model type as well, and if you want to reset the parameters, you just push and hold one second and it resets all the parameters in there back to the defaults. So you can also change the type of aircraft. You can do gliders. You can do helis, you can also do RC cars. This is SS Aero basic, but that would be essentially like an aerobatic plane and you have three different versions of gliders in here. I believe so I'm going to set that back to the standard aircraft. Firm and that's for my multirotors now I'm going to go back out of here and we'll go to end points, and this is nice because it's very very easy to go in here and change your in end points and you can see it's a nice simple menu Here and you can see what everything is set to 100 values and 75 on the bottoms they're very nice and I'll go back out of there. I'Ll, go into sub trim and again very simple, menus vertically stacked and easy to get to just turn that dial wheel and you can make any changes there. Now we can reverse servos we go in here. We have the stack again very, very simple and right here we have normal.

If I want to switch the aileron direction, I press and hold and it'll. Let me change from reverse to normal, so there I can reverse and I'll. Ask me, Είμαι, I sure, I'm, just going to leave it on normal it's, going to set that to default now, I'm going to go back out and we'll go to the dual rate in Expo very nice simply to change your dual rates? If you go down here, you can change your expo as well. Now a motor cut another simple menu in there inhibit or activate trem setup, πολύ απλό, and we can go in here also let's set those parameters auxilary. We can change some switch setups in here and we can add a timer as well. So if you know you have five minutes on battery for that specific model, you can change how long your beeper is set up for so five minutes. That will give you a beep or you can do a vibration, which is kind of nice train report switch. This is the menu for that you can go in here and set that up as well. So the dial will is very sensitive, have get kind of used to that and you can change up your mix and your your surface set up there and now I'll go down to servo setup, and this is another way you can test your servos. If you want to get in here and move these gimble's around you'll see the travel adjustments on your sort of different servos that you have once you plug in your receiver.

You'Ll see more info on that, and now your receiver can go in here, and this is this is where it gets interesting. Folks we have, all of this. Information on here can be telemetry coming from your receiver in your aircraft, so you're going to get battery voltage. Your current throttle latitudelongitude, if you have GPS your altitude in there as well, and your yaw roll and pitch and distance from the transmitter and and all this is pretty cool. If you have GPSand you can you can change that in this setup, so that's a very, very intuitive telemetry interface that we have on here. So if you have OSD, it'll also show all your OSD parameters right on the radio, so that's very useful, especially if you have a crash and have GPS onboard, you can tell where it crashed. The last known recorded point now go down to system, settings and we'll go in here, and this is where it also gets even more interesting as well. So we have a shutdown after 256 λεπτά. You can also change the background of the screen. If you want this to change, white click that button and you can change the whole interface to something a little brighter, I kind of like the black myself so I'm going to leave it on black. Εγώ, like that, a lot now our SSI alarm. This is nice too, because if you lose transmission from your receiver and you lose contact with your aircraft, you can set an alarm on there and it will actually beep.

Για να μπορέσεις να.. You can set that to the exact parameter DBM on your receiver and that's kind of cool, so we'll go back out of here and I'll go all the way back out and that's pretty much. The fundamentals of the menus on the radio Lincoln is the 1890s and it's it's, actually a fairly intuitive radio to work with one of the easier radios that I've used. Κατά τη γνώμη μου, Εντάξει, just to sum it up guys, I got to tell you that playing around with this radio, I was able to figure it out in about five to ten minutes and just going into these menus and spinning it around in here. It is really simple layout in the menus very intuitive and easy to use. When I first looked at it, I thought oh, no here's, another transmitter I'm going to have to figure out for the next like three months before I can do a decent review on it. For you guys, but compared to much Ranas Plus, this was way easier to use and bind up for the first time setting up the receivers was really intuitive, especially with this little bind button on the side. I don't have to fight with it with my Terrenas. ενίοτε, when I go to bind it up, press and hold the switch and then you know power up a battery and then I have to to wait for it to flash green. Sometimes it binds, and sometimes it doesn't, which drives me a little bit crazy, but sometimes I'm probably doing the process wrong.

But the nice thing about this one is you turn on the radio you power up your receiver and you press this and hold it and it automatically finds it which is really really nice. So this light, the status light will change to red once it's bound up and blue. If it's SBUs, you press this button again to change it into Espoo so and, like I said they do have a variety of different receivers available for the 89 s and the 89 and they're all competitively priced. Εννοώ 12 για να 15 for a receiver is not bad and there's plenty of range with these, so you don't suffer any range loss using the radio link receivers and the nice thing is you don't have to have any binding plugs in here or press it down And hold it while you're trying to plug in the battery at the same time on your quadcopter, so this is going to be a lot easier to bind up your receivers. The radio interface itself is all color screen and I can change a variety of things in there if you're, like most of it, is really customizable to change it to the way I want it. So this is a very optimal radio for me to use. I think this is going to be something that I'm probably going to use myself and link up with some my other aircraft. I might actually hook this up to one of my wings that I have sitting there waiting for a receiver so I'm going to do some testing with that coming up this winter.

So thanks again for watching this review guys, I hope that it showed you some of the features that 89s and hopefully how much better it is than the original 89, so I'm Justin Davis from drone camps thanks again for watching us and joining us on the channel.
